Description
Description RETROFIT ELECTRICAL SYSTEM FOR DOCKSIDE POWER PEDESTALS
Technical Field [0001] This invention relates generally to electrical connector assemblies used in dockside electrical power pedestals, and more particularly concerns a retrofit electrical assembly for such power pedestals.
Background of the Invention
Technical Field [0001] This invention relates generally to electrical connector assemblies used in dockside electrical power pedestals, and more particularly concerns a retrofit electrical assembly for such power pedestals.
Background of the Invention
[0002] Electrical power units, frequently referred to as power pedestals, are provided at dockside installations, such as along piers, for boats and other marine vessels. Electrical connections are provided between the power pedestal, which is connected to a land-based power supply, and the pedestal. Such power pedestals are well known, with various configurations, and typically have electrical connections for both 30 amp and 50 amp power. Boats and other marine vessels can thus obtain power from a dockside source for their boats rather than use their own battery power.
[0003] Present power pedestals, however, have several disadvantages. They are open to the weather, even those units which have a lid or the like to cover the actual electrical receptacles/connections or sockets. Weather typically produces corrosion in the receptacle, even with a lid removably covering the receptacles, interfering with performance and presenting a significant fire hazard. Fires cause damage to the pedestal as well as possibly the dock. It is a significant issue for marine facilities using power pedestals with a land based power supply.
[0004] Accordingly, the present invention is directed toward producing a receptacle arrangement for existing power pedestals which is protective against the weather and the fire hazard of existing power pedestals as well as being easy and convenient to use.
Summary of the Invention
Summary of the Invention
[0005] Accordingly, the retrofit receptacle assembly for replacing an existing power receptacle on a dockside power pedestal, comprises: a receptacle assembly having a housing member and an inner portion which extends from the housing member outwardly beyond a forward Date Recue/Date Received 2020-11-17 edge of the housing member, defining an asymmetrical opening therebetween, the inner portion having a forward surface with female openings to receive therethrough male electrical probe members from a male connector, which in turn is connectable to a power supply on a boat at dockside; electrical connector elements positioned within the housing member with connections to receive electrical power from a power pedestal source; and a mounting assembly for securing the retrofit receptacle assembly housing to a mounting element present in the existing power pedestal.
[0005A] Accordingly, the retrofit power receptacle assembly adapted to replace an existing power receptacle present on a dockside power pedestal, comprises: a retrofit power receptacle configured to be secured to a dockside power pedestal, following removal of an existing power receptacle present on the dockside power pedestal, the retrofit power receptacle having an outer housing member and an inner portion which extends from the outer housing member forwardly beyond a forward edge of the outer housing member, defining an asymmetrical opening between the outer housing member and the inner portion, the inner portion having a forward surface with female openings to receive therethrough male electrical prongs from a separate male connector assembly connecting to electrical connections within the inner portion, providing electrical connection between the retrofit power receptacle and the male connector assembly, which in turn is connectable to a power supply on a boat present at dockside; wherein the electrical connections within the inner portion of the retrofit power receptacle receive electrical power from a power source in the dockside power pedestal; and a mounting assembly to which the retrofit power receptacle is secured, wherein the mounting assembly is securable to the dockside power pedestal from which the y existing power receptacle has been removed, wherein electrical power from the power source in the dockside power pedestal is thereby provided to the retrofit power receptacle.

Best Mode for Carrying Out the Invention
Best Mode for Carrying Out the Invention
[00030] Figure 1 shows an example of a power pedestal, a well known article which is positioned dockside and provides electrical power to boats. The pedestal 10 receives power from a conventional land-based supply.
[00031] The pedestal 10 can include a number of specific features, including a light 12, a housing 14 and other features, such as water connections and phone or cable TV
connections (not shown). Often, the pedestal will include 30 amp and 50 amp power receptacles 16 and 18 (Figure 2) which are typically, but not always, covered by a lid 20. The power lines extend down at an angle through openings 17 and 19. In some cases, the receptacles are open to the weather. As previously indicated, even with a lid, the power receptacles are vulnerable to weather, which leads to corrosion in the electrical connections within the receptacle. Corrosion Date Recue/Date Received 2020-11-17 typically leads to failure or poor connectability and reliability, and in some cases may result in fire, which damages the receptacle and quite possibly the boat dock.

Corrosion Date Recue/Date Received 2020-11-17 typically leads to failure or poor connectability and reliability, and in some cases may result in fire, which damages the receptacle and quite possibly the boat dock.
[00032] Referring now to Figures 4A and 4B, Figure 4A shows an exploded view of a retrofit receptacle assembly 27 from the rear for a 30 amp receptacle, while Figure 4B shows a front/forward view of the retrofit receptacle assembly. The 50 amp retrofit receptacle assembly is similar. The receptacle assembly 27 includes a housing member 28 which includes a generally octagonal shaped outer surface approximately 2.5 inches from side-to-side and approximately 7/8 inch from back to front. Housing member 28 surrounds an inner portion 30 having a non-symmetrical outline, matching a non-symmetrical outline of an inner surface 32 of the housing member, with a space of approximately 3/8 inch therebetween.
[00033] In the embodiment shown, referring to Figure 4C, the non-symmetrical outline includes two opposing parallel side surfaces 31, 33, a flat bottom surface 34 joining the two side surfaces, two upper angled surfaces 36 and 37 and two lower angled/curved surfaces 38 and 39.
The non-symmetrical configuration, however, can be varied. The inner portion 30 extends forwardly of the forward edge of the housing member 28 approximately 3/4 inch.
The inner portion 30 includes a front flat surface 40. Located in the front surface 40 are three openings, 39, 41 and 43 which are adapted to receive corresponding male electrical prong connection members therethrough. Positioned between inner portion 30 and housing member 28 is a seal 42. Seal 42 can be composed of rubber or other material, to seal the forward end of a male connector 49 (Figure 5B) against the seal between housing member 28 and the inner portion 30 of receptacle assembly 27. Housing member 28 includes an upper locking assembly 43 and two side locking assemblies 45 and 47. The upper locking assembly 43 includes an upper spring-loaded locking element 48 which is secured in a cavity 50 in housing 50a by two screws 51 and 52. Between upper locking element 48 and the upper portion of the cavity 50 is a spring element 54, which tends to hold the upper locking element 48 in a down position. The upper locking element 48 includes a protrusion 55 which fits into a groove in male connector 49 as discussed below.
The non-symmetrical configuration, however, can be varied. The inner portion 30 extends forwardly of the forward edge of the housing member 28 approximately 3/4 inch.
The inner portion 30 includes a front flat surface 40. Located in the front surface 40 are three openings, 39, 41 and 43 which are adapted to receive corresponding male electrical prong connection members therethrough. Positioned between inner portion 30 and housing member 28 is a seal 42. Seal 42 can be composed of rubber or other material, to seal the forward end of a male connector 49 (Figure 5B) against the seal between housing member 28 and the inner portion 30 of receptacle assembly 27. Housing member 28 includes an upper locking assembly 43 and two side locking assemblies 45 and 47. The upper locking assembly 43 includes an upper spring-loaded locking element 48 which is secured in a cavity 50 in housing 50a by two screws 51 and 52. Between upper locking element 48 and the upper portion of the cavity 50 is a spring element 54, which tends to hold the upper locking element 48 in a down position. The upper locking element 48 includes a protrusion 55 which fits into a groove in male connector 49 as discussed below.
[00034] Housing member 28 also includes two side locking elements 45 and 47 which are flexibly attached at their rear edges to the housing member. The locking elements 45 and 47 fit into mating grooves/openings on the male connector 49. Figures 4B and 5A show the side Date Recue/Date Received 2020-11-17 locking elements. The side locking elements, respectively, are configured to fit with a frictional fit in groove 61 on one side and an opposing similar groove on the other side of the male connector 49. The frictional fit is sufficient to hold the male connector 49 in place in the receptacle assembly 27 but permits the male connector to be pulled out by hand force from receptacle assembly 27. The combination of the spring loaded upper locking element and the two side frictional fit locking elements 45 and 47 hold the male connector 49 securely in place relative to the receptacle assembly 27.
[00035] The housing member 28 and inner portion 30 are in the embodiment shown made of heavy duty plastic. As indicated above, the inner portion 30 extends forwardly beyond the forward edge of the housing member, and as discussed above, the male connector 49 can be fitted within the opening between the inner portion 30 and the housing member 28. As shown in Figure 4A, electrical wires from the power pedestal are connected to three wire connectors 62, 63 and 64 on the inner portion. A threaded portion 68 has a front plate 70 which fits into a cavity at the rear of the housing member 28. The threaded portion 68 fits back through an opening in the mounting plate of the power pedestal, with the rear surface 72 of front plate 70 coming into contact with the mounting plate. A cap 74 is threaded onto the threaded portion 68 holding the retrofit receptacle assembly in place to the mounting plate in the pedestal.
[00036] Figures 5A-5C show an assembled receptacle assembly and a mating male connector assembly as shown in previous figures, with a male end of the connector adapted to mate with the non-symmetrical opening of the receptacle assembly. Figures 5A
and 5C show a male connector with three extending prongs 86, 88 and 90 which are configured to fit tightly into the openings in the receptacle assembly, providing electrical connection between the receptacle assembly and the male connector assembly. Figure 5C shows a front end view of the male connector. Figures 5A and 5B show a lever 96 on top of the male connector. The forward end 98 of the lever 96 fits under the forward edge of the upper locking element 48 when the male connector is positioned in the receptacle assembly. When the lever 96 is pushed downwardly, the upper locking member 48 is moved upwardly against the resistance of spring 54, releasing the upper locking member. As indicated above, the flexible side locking elements 45 and 47 on the housing member fit into receiving side grooves on the male connector. The contact is tight enough to prevent accidental disconnect, but can be pulled apart without great effort. The above Date Recue/Date Received 2020-11-17 arrangement provides a water-tight seal against the elements between the receptacle assembly and the male connector and a reliably tight fit between the male connector and the receptacle assembly.
When the retrofit receptacle assembly is not in use, the lid 20 on the power pedestal is simply moved down over the receptacle assembly.

When the retrofit receptacle assembly is not in use, the lid 20 on the power pedestal is simply moved down over the receptacle assembly.
[00037] Figures 5D and 5E illustrate the use of a thumb screw 100 which is threaded through housing 50a and the upper part of spring 54. When the thumb screw 100 is in its down most position, the lever 96 on the male connector cannot release the upper locking element 48, thereby maintaining the upper locking element securely in place. This is an additional safety feature preventing unintended disconnect of the male connector from the receptacle assembly.
[00038] Figures 6A through 6G show a water resistant weather proof cover for the retrofit receptacle assembly. The water resistant cover includes a back plate 102 and a hinged cover element 104. The back plate 102 can be attached to a conventional or other pedestal at the dock.
The cover 104 is pivotally connected to the upper exterior surface of the back plate by a pivot assembly 106. The cover fits over the housing member of the retrofit receptacle assembly 107 providing reliable protection against the elements. The cover includes a small tab 108 at a lower end thereof which fits into a corresponding opening 109 at the lower edge of the receptacle assembly when the cover is in a closed position. Figure 6D shows this connection most clearly.
When a connection between the receptacle assembly and the male connector is desired, the cover 104 is pulled away and swiveled upwardly about the pivot assembly 106, exposing the inner portion of the receptacle assembly for connection. Figure 6E shows a male connector 112 connected to power receptacle assembly 107 with cover 104 in an open position.
Figure 6F shows cover 104 in a closed position, in which tab 108 now fits into a locking groove 113 in the surface of the male connector 112. This is shown most clearly in Figure 6G. Cover 104 locked into groove 113 in the male connector, helps to prevent unintended disconnect.

[00039] Figure 7 shows a typical connector arrangement involving a pedestal outlet assembly with a retrofit receptacle assembly 118 and a cover assembly 119 and a boat inlet assembly 117 with a cover assembly 121 and an intermediate connector assembly 120. The pedestal assembly receptacle 118 has a female configuration while the boat inlet assembly 117 has Date Recue/Date Received 2020-11-17 a male configuration. The length of the connector assembly 120 is variable.
The direction of current flow is from the pedestal outlet assembly to the boat inlet assembly.
The direction of current flow is from the pedestal outlet assembly to the boat inlet assembly.
[00040] While the embodiment of Figures 4A-4B show a weather seal 42 between the housing member and the inner portion which the forward edge of the male connector contacts, other seal arrangements can be used. In the one example shown in Figures 4A-4B, weather seal 122 can be positioned behind the rear surface of the inner portion and the mounting plate for the receptacle assembly. Other sealing arrangements can be used as well.
[00041] Figure 8 shows an arrangement with a connector 126 with an adapter arrangement 128 for an older style connection to a boat or RV such as a twist connector or other type of connection.
[00042] Figure 9 shows an alternative for locking a male connector 144 to a retrofit receptacle assembly 145. At a forward edge 130 of housing member 132 is an actuator member 134. Extending along the outer edges of the housing member are two side locks 136 and 138, mounted to hinge elements 140 and 142, respectively. The male connector 144 includes thumb lever 146 on the top of connector 144. When the male connector engages the retrofit receptacle assembly, the side locks engage openings in the outer surface on the male connector 144, locking the male connector to the retrofit receptacle assembly 145. The forward end 147 of lever 146 fits under the actuator 134. When the male connector is to be released, thumb lever 146 on the male connector is pushed down. The lever 146 acts on the actuator 134 so that both side locks swing out, permitting disengagement of the male connector from the retrofit receptacle.
